Hi all, I'm in the process of upgrading a lot of the bus electrical. Magnum 4024, 8 batteries, ATS, etc. I know the neutral and ground should not be bonded on an RV, but I am seeing conflicting information online concerning grounding the AC power to the bus chassis. I would think this ground, much like the DC system, would be tied to the chassis. Is this correct? Thanks
The ground gets tied to the bus chassis. The neutral does not.

Tom gave you the answer, but there is more good stuff...
it's a little more complicated than that. The neutral and ground are to be bonded together at the source, meaning when you are running power from that 4024, it should be
bonded at the inverter. The inverter may or may not bond it, and if it does, you need to break it when you plug into shore power. When on shore power, the neutral
and ground should NOT be bonded in the bus. If you have a generator, then like the inverter, it should be bonded at the generator when running.
And ground should always be bonded to the chassis. Your electrical panel may be mounted to the bus chassis, which will bond the safety ground which is on a separate
strip which is attached to the panel box.
I couldn't agree more. Mike explains this topic better than anyone else I've ever read. The last thing you want to do is end up with a "hot skin" on your conversion and Mike will explain how and why to avoid this condition. If you are using a portable genny to power your rig you will want to check with the mfg as to whether or not the unit has a floating ground. If it does, follow Mike's advice as to how to correct this situation. Jack

In fact Mike S. will answer personal Email questions.. at least he did mine, tho that was a while back ;D
